The theory of magnetohydrodynamics (MHD) models the interaction between magnetic fields and the motion of electrically conducting fluids [1]}. Such models are ubiquitous in astrophysical systems [2]}, [3]} including the dynamics of interstellar dust clouds [4]}, [5]} and the dynamo effect responsible for the generation of planetary magnetic fields (including that of the earth) [6]}, [7]}, [8]}. One of the most heavily researched astrophysical applications of MHD is in solar physics [9]}, for-instance the formation of stars [10]}, [11]}, the coronal heating problem [12]}, [13]}, [14]}, the behaviour of the solar magnetic field [15]}, [8]}, and the modelling of solar flares [17]}, [18]}. MHD is regularly applied to the physics of nuclear reactors, such as in the modelling of plasma dynamics in fusion reactors [19]}, or that of liquid metal coolants in both fission [20]} and fusion [21]} reactors. Magnetohydrodynamical theory is also increasingly being applied to industry [22]}, [23]} where magnetic fields are used to heat, pump, and control the flow of liquid metals.
